**MathMate**, Wednesday, September 2, 2009 at 7:45pmTake the first equation and solve for x:

2x-9y=2

x=(2+9y)/2

Substitute this value of x into the second equation and solve for y.

Substitute the solution for y into the first equation to find the solution of x.

BACK SUBSTITUTE x and y into both equations to make sure the answer is correct.
